Army unveils new tank—five years early

Built largely of commercial parts, the first M1E3s will head out for testing this summer, the Army’s chief of staff said.

DETROIT—Car enthusiasts milling around the floor at the Detroit auto show this week will get the first public glimpse of the Army’s new main battle tank, as the service prepares to roll out its M1A1 Abrams replacement five years ahead of its original timeline. 

Rather than wait to field the vehicles until every last sensor and radio is determined, the Army cut the tank’s development time way down by getting the physical vehicle built and allowing the bells and whistles to be installed and upgraded as the technology evolves.

“The way we used to look at all these boxes…we used to take that box and install the computer,” Col. Ryan Howell, the Abrams’ project manager, told reporters Wednesday. “Today, it's computer first, and it happens to be hardware second. So the box doesn’t matter.”

With that in mind, the Army is putting “the box” into soldiers’ hands to make sure it maneuvers the way a tank platoon needs it to, and to gather feedback on what it needs for communications, weapons, and sensors.

“Rather than focusing on the tank, we focused on all the digital backbone and the software and what it's supposed to do, and then we wrapped a tank around it,” said Alex Miller, the Army’s chief technology officer. “So the fact that the hull looks similar is because we figured out a long time ago, that's what armor should look like to be effective.”

All of the cameras, the counter-drone systems, the gunnery and so on will evolve based on the best commercially available tech.

“So now Col. Howell and the acquisition team can update our tank in days and weeks on the software side, rather than us taking a year,” Miller said.

The vehicle itself is made of commercial parts: a Caterpillar engine, SAPA transmission, and a Roush race car cockpit with embroidered Recaro seats.

It sounds pretty fancy for the Army, but it turns out that using all of these commercial products to build the new tank cut down significantly on the price tag.

“I won't give you the exact dollar figure, but they can produce them at 10-percent the cost—with the embroidery,” Howell said of the luxe seating.

The M1E3 is the biggest program yet developed under the Army’s new Continuous Transformation acquisitions model, which eschews exquisite, bespoke systems that take decades to develop and lock the Army into the hardware, software and the company that builds them.

Instead, the Army has ordered four of the prototypes from Roush, who in their partnership with General Dynamics used the existing Abrams specs to build the vehicle’s skeleton. General Dynamics will take the lead on the next round of test vehicles. 

“So I think it would be, you know, a vendor comes and says, ‘Hey, I've got something that's better for active protection. There's a better engine, there's a lighter transmission to meet those specs.’ They could, you know, plug in and play in that,” Gen. Randy George, the Army’s chief of staff, told reporters.

Those specs include a total weight one-quarter less than today’s 70-plus-ton Abrams. It also has a hybrid-electric engine that sips half the fuel while delivering a top speed of about 40 mph.

“So it doesn't have a fast quarter-mile time, but it can knock out a target at a quarter-mile in about a tenth of a second. You know, shoot an apple off a fence at 3-plus kilometers,” George said. “You can kill drones, do the kinds of things that we would expect of a system like that out there, and you could put it anywhere in the world to do that.”

The Army has also spent a lot less money than usual before getting it into soldiers’ hands. About $75 million bought the research and deent, the software architecture inside the tank, and the first production models.

The service has asked for more than $700 million in this year’s budget to start expanding the work. It will take a couple years to get enough built to start sending them out to every tank unit, but the Army was originally planning that it wouldn’t even have soldiers testing them until 2031.

With that initial feedback expected to start coming in this summer, officials are comfortable taking the resources they would have spent on finding the perfect sensors and sights and radios before testing and spending it on the back end, to continuously upgrade the M1E3 as soldiers test it in the field.

And George hopes to be able to repeat this success with its forthcoming M2 Bradley replacement. 

“It's one of our goals that we're back here next year, and sitting in the same room having the same discussion with an XM-30 that’s down there,” he said.
